co-presence in the on-line media events

How do people react when they watch the “Super Bowl” game in crowds and in a stadium ? How could the situation differ when they watch the game on TV within a much smaller group? What about the reaction when people watch the game alone online? It is interesting that these three situations have something in common–the audiences’ co-presence to the same media event, however the co-presence doesn’t have to be in any single or particular venue.

How could we get access to and follow the online co-presence? What are the possible implications of DH approach to study people’s changing reception?
